DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] As shown in FIG. 1, the present invention provides a wirelessreceiving device jointly used by computer peripherals. The wirelessreceiving device 1 of the present invention can be used to receivewireless signals emitted by wireless emitting devices of differentcomputer peripherals, and has learning function. The wireless receivingdevice 1 comprises a wireless receiving circuit 11, a micro-processingcircuit 13, an interface circuit 15, a reset circuit 17, and anoscillation circuit 19.

[0015] The wireless receiving circuit 11 is used to receive wirelesssignals emitted by wireless emitting devices. The wireless receivingcircuit 12 adopts the frequency shift keying (FSK) modulation techniqueto enhance anti-noise capability. The wireless emitting device can be awireless keyboard 2, a wireless mouse 3, a wireless remote controller 4(shown in FIG. 4), or another wireless emitting device.

[0016] The present invention will be illustrated with the wirelesskeyboard 2, the wireless mouse 3, and the wireless remote controller 4as examples of wireless emitting devices. Each wireless emitting devicehas an ID code representing its identity, and the ID code is composed ofa product code and an identity code. In other words, different kinds ofwireless emitting devices are distinguished according to differentproduct codes, and different wireless emitting devices of the same kindare distinguished according to different identity codes.

[0017] The micro-processing circuit 13 is used to identify and decodethe received wireless signal to distinguish the kind of the wirelessemitting device and the transmitted message, and convert them into acontrol signal. The wireless signal is composed of the ID code and data.The data is used to represent action message emitted by the wirelessemitting device.

[0018] The interface circuit 15 is connected between the output end ofthe micro-processing circuit 13 and a computer, and is used to receivethe control signal and then output it to the computer. The interfacecircuit 15 is connected to a transmission port conforming to theuniversal serial bus (USB) protocol of a computer.

[0019] The reset circuit 17 is composed of a resistor R1 and a capacitorC1, and is connected to the input end of the micro-processing circuit13. The reset circuit 16 is used to initiate the micro-processingcircuit 13.

[0020] The oscillation circuit 19 is composed of capacitors C2 and C3and a quartz crystal Y1, and is connected to the input end of themicro-processing circuit 13. The oscillation circuit 17 is used toprovide the working frequency.

[0021] The above wireless receiving device 1 can be used to receivewireless signals emitted by various kinds of different wireless emittingdevices. The learning procedure can be activated to memorize and lock ona device under the situation that there are several wireless emittingdevices of the same kind. For instance, if there are mice A, B, and C,and the wireless receiving device 1 only receives message emitted by themouse A currently, in order to switch to the state of only receivingmessage of the mouse B, it is only necessary let the mouse B functionand the mice A and C not function. After the wireless receiving circuit12 receives a wireless signal emitted by the mouse B, the learningprocedure will let the micro-processing circuit 13 memorize the ID coderepresenting the mouse B and lock on it. That is, the wireless receivingdevice 1 only receives message emitted by the mouse B afterwards.Therefore, using this learning procedure, different users can have theirindividual mice. It is only necessary to activate the learning procedureto let the mouse in the hand function.
